Target

Function

Receptor for ATP that acts as a ligand-gated ion channel. Responsible for ATP-dependent lysis of macrophages through the formation of membrane pores permeable to large molecules. Could function in both fast synaptic transmission and the ATP-mediated lysis of antigen-presenting cells.

Tissue specificity

Widely expressed with highest levels in brain and immune tissues.

Sequence similarities

Belongs to the P2X receptor family.

Post-translationalmodifications

Phosphorylation results in its inactivation.ADP-ribosylation at Arg-125 is necessary and sufficient to activate P2RX7 and gate the channel.Palmitoylation of several cysteines in the C-terminal cytoplasmic tail is required for efficient localization to cell surface.

IHC image of ab109054 staining in rat brain formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab109054, 0.1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
